QMA Series Connectors

Cinch Connectivity Solutions offers the Johnson product line of QMA connectors that feature a push-on style interface. Traditionally, SMA plugs need to be configured with extra space allowance for torque wrench coupling procedures. The QMA connectors are designed for higher density packaging situations with the push-pull connector interface allowing for more connectors per application. Johnson's unique coupling spring provides excellent electrical performance and consistently low voltage standing wave ratio (VSWR) and insertion loss parameters. All designs are based on 50 Ω system impendence and operate at frequencies up to 12.4 GHz.

Connector bodies are offered with a tri-alloy as a standard finish and gold plating where soldering is required. All contacts are plated with 50µ" of gold for excellent durability and high frequency performance.
